1. INTRODUCTION
1.1 Purpose
i.MX6UL/i.MX6ULL SODIMM Development platform incorporates i.MX6UL/i.MX6ULL SODIMM SOM and SODIMM
Carrier board for complete validation of i.MX6UL/i.MX6ULL SODIMM SOM functionality. This document is the
Hardware User Guide for the i.MX6UL/i.MX6ULL SODIMM Carrier Board. This Guide provides detailed information on
the overall design and usage of the SODIMM Carrier Board from a Hardware Systems perspective. Complete
information about the i.MX6UL/i.MX6ULL SODIMM SOM hardware is explained in other document
“i.MX6UL/i.MX6ULL SODIMM SOM-Hardware User Guide”.
1.2 Overview
iWave's i.MX6UL/i.MX6ULL SODIMM Development Board incorporates i.MX6UL/i.MX6ULL SODIMM SOM which is
based on NXP's power efficient i.MX6UL/i.MX6ULL ARM Cortex A7 processor and the SODIMM carrier board with
optional 4.3" resistive display kit. The development board can be used for quick prototyping of various applications
targeted by the i.MX6UL/i.MX6ULL processor. With the 100mmx72mm Pico ITX size, the kit is highly packed with all
the necessary on-board connectors to validate the i.MX6UL/i.MX6ULL CPU features.
